COUPLING nnvron.

Application filed November 3, 1926. Serial No. 146,050.

My inventionrelates to coupling devices. It is the object of myinvention to provide a coupling device which will automatically operatein the making of the coupling and in which the coupling member will movedownwardly in the coupling operation and uncoupling operation, therebyallowing a load to be placed over the coupler without interfering withthe coup-lers movements.

It is a further'object to provide a coupler which may be operated by thehand or foot of the operator when it is desired to uncouple the couplersbein so arranged that this is possible without respect to the locationof the load on the truckwith which the coup ler is a part. I

Referring to the drawings:

Figure 1 is aside elevation of a truck with one portion of the couplingunit which is placed upon the handle of the truck in section;

I Figure 2 is a side elevation of the springactuated coupler partiallyin section to show the arrangement of the spring; I

Figure 3 is a section through the release projection on the couplerhead; 7

Figure 4: is a section through the complete coupler combination.

Referring to the drawings in detail, 11 are wheels supporting a truckframe of any desired kind. The type of vehicle is not important. I

Mounted. upon the rear end of this frame is a casting constituting thecoupler head. This casting consists of a supporting portion 3 mounted inthe frame 2 of the vehicle. The supporting portion 3 has a pair ofoutwardly extending spaced parallel portions designated 4, through whichpasses transversely a shaft 5 supporting the coupler hook arm 6. Thishook arm is provided with an internally disposed space 7 on one side ofwhich is the eye 8 for mounting the hook on the shaft 5 and on the otherside of which is a partition 9.

In the space thus formed by the side walls of the hook 6 is located ahelical spring 10,

the bottom of which is supported on a transverse bottom plate 11 carriedbetween the side walls 4. At the top, the side walls are closed by theguide plate 12 which projects rearwardly having a downwardly andforwardly extending cam face 13, against which the eye 14: of the handle15 rests and along which it travels as it passes by the nose 16 of thehook into the space designated 17 which is the finally locked engagingposition.

This hook 16 is provided with the arcuate face on the exterior thereof,designated 18, on which this eye '14 rides into engagement with the face18. A depending loop 19 is provided, which may be engaged by the hand orfoot of the operatorfor depressing the hook to permit the coupling to beuncoupled.

It will be understood that I desire to comprehend within my inventionsuch modifications as may be necessary to adapt it to varying conditionsand uses.

Having thus fully described my invention, what I claim as new and desireto secure by Letters Patent, is

.1. In a coupler, a frame having a hook supporting portion and astationary eye guiding portion, a hook mounted therein, yielding meansto maintain said hook in engagement with said guiding portion, whereby.the eye may be pressed againstthe exterior of said hook passing over theend thereof along the guiding portion to a point behind the hook intolocking position.

2. In a coupler, a stationary supporting and guiding member, a hookmember and yielding means to maintain said hook member normally inlocking position and means carriedon said hook member for moving it tounlocked position.

8. In a coupler, a supporting member having a stationary guidingsurface, a hook pivoted thereon, yielding means to maintain said hook inlooking position, said hook and guiding surface of the supporting memberbeing below the loading surface of the vehicle to which said coupler isattached.

4i. In combination in a coupler of a sup porting member adapted tosupport a coupling hook and having an overhanging ledge, the uppersurface of which is adapted to support a load, a coupling hook pivotallysupported on said member beneath said surface, a stationary guidingsurface on said member disposed adjacent the nose of said hook andyielding means to maintain said nose in engagement with said surface.

5. In combination in a coupler of a supporting member adapted to supporta coupling hook and having an overhanging stationary ledge, the'uppersurface of which is adapted to support a load, a coupling hook pivotallysupported. on said member beneath said surface, a guiding surface onsaid member disposed adjacent the nose of said hook and yielding meansto maintain said nose in engagement with said surface, and means fornormally engaging said hook to move it to uncoupling position.

6. In combination in a coupler of a supporting member adapted to supporta coupling hook and having a stationary overhanging ledge, the uppersurface of which is adapted to support a load, a coupling hook pivotallysupported on said member beneat-h said surface, a guiding surface onsaid member disposed adjacent the nose of said hook and yielding meansto maintain said nose in engagement with said surface, and means fornormally engaging said hook to move it to uncoupling position, saidmeans consisting of a loop projecting from said hook.

7 In combination in a coupler, means for attaching the coupler to avehicle, a hook supporting portion for a hook consisting of spaced sidewalls and a transverse bottom, a hook pivoted therebetween, said hookhaving an internally disposed downwardly opening socket, a springlocated in said socket and between said hook and said transverse bottom,a downwardly disposed stationary guiding face mounted above said hook onsaid hook supporting means adapted to guide an eye over the end of saidhook into locking position and an eye for that purpose in combinationwith said coupler mechamsm.

8. In combination 1n a coupler, means for mazees attaching the couplerto a vehicle, a hook supporting portion for a hook consisting of spacedside walls and a transverse bottom, a hook pivoted therebetween, saidhook having an internally disposed downwardly opening socket, a springlocated in said socket and between said hook and said transverse bottom,a downwardly disposed stationary guiding face mounted above said hook onsaid hook supporting means adapted to guide an eye over the end of saidhook into locking position and an eye for that purpose in combinationwith said coupler mechanism, said hook having an arcuate head directedupwardly and inwardly towards said guiding face first mentioned wherebythe eye is guided to the guiding face by the head of the hook.

9. In combination in an automatic coupler, a hook support, a hook havinga guiding head, said support having a stationary guiding face adjacentthe nose of the hook and yielding means for maintaining said hooknormally in looking position with its nose against said guiding face.

10. In combination in an automatic coupler, a hook support, a hookhaving a guiding head, said support having a stationary guiding faceadjacent the nose of the hook and yielding means for maintaining saidhook normally in locking position with its nose against said guidingface, and a depending member to permit of the manual operation of saidhook.

In testimony whereof, I affix my signature.
